Harmonics.I have read repeatedly that bayonet chronos will affect POI. Will they affect group size or shape as well?
338 dude, can you do a close up of how you have the bipod and Wiser mounted? I have the Wiser and run a harris bipod but am having heck getting it all set up. I'm about to the point of selling the Wiser mount. I do have a pic rail on my Oryx chassis, but getting it all aligned and getting the sporter bayonet close enough, it almost touches my barrel has become quite frustrating.I still have an use a magneto speed myself With a mount from wiser Precision
AS are mine. I was pleasantly surprised that the groups were still quite good. As mentioned earlier, I use mine only to find the SD/ES "sweet spots".My poi shift is minimal but my groups are still solid.
I have no change in group size or POI on any of my heavy barreled rifles. My one sporter barrel has a predictable POI shift high and left.I have read repeatedly that bayonet chronos will affect POI. Will they affect group size or shape as well?
I see an impact shift of about an inch or so at 100 but that doesn't bother me too much when doing load development. I'm only looking for a speed node and don't care where or how it groups. But if you do want to shoot groups while checking velocity or if you are shooting a suppressor. Wiser Precision has a carbon fiber rod that allows you to get off the barrel and adapts to a picatinny or arca-swiss rail. Costs about $100, light weight and tool-less. Check it out. https://www.wiserprecision.com/products/chrono-mount
My buddy has the same issues your stating plus takes him much longer to set up and its pretty finicky. Although, once its set up and you remember to arm it after every shot it actually does a great job. Hard to justify $700 for this technology right now. I am sure someone will get it perfected but till then I'll just use that $700 on powder, bullets and brass and stick with my MS.I have the MS with the Wiser Precision standoff. I ordered a LabRadar with all the extras needed to make it functional while I was waiting for a new bayonet after nicking the second sensor on the MS.
Here's what I have learned..
Magneto Speed functions perfectly 100% of the time and is easy to use.
The Wiser Precision standoff has some issues. The little springs pop off never to be found. The guy that makes it suggested gluing one end of the spring to the little hole on the part that moves. That seems to work ok.
It requires a picatinny rail to attach it to the rifle stock. Afixing a picatinny rail to a sporter rifle stock using the sling stud was a big problem for me. I had to shim it and it wasn't stable enough resulting in a ding that cost $170 for new bayonet. I'm sure someone has engineered a better solution than I did. The WP standoff works well with my chassis rifles. But you still have to pay attention to the clamp staying snug.
The Labradar with all the goodies ( battery, battery holder, pouch to carry it, tripod mount, sd card, recoil trigger, aiming device which evolved into red dot sight and 3D printed holder to get the orange box to pick up 95% of the shots) cost north of $700.
Also, which I didn't appreciate until it was too late, the Labradar won't pick up anything over 3900f/s. So much for chronographing my 204 Ruger and 22-250 Rem
Recording shots IMHO is a PITA. The recoil trigger picks up bogus data when ejecting shells or loading shells or maybe just to screw with me.
I know a lot of folks really like their Labradar. I'm just not one of them.
